smokeping 微信报警配置

1. 准备alert脚本，用来调用微信脚本

#!/bin/bash

alertname=$1
target=$2
losspattern=$3
rtt=$4
hostname=$5

smokename="hq_to_idc "
if [ "$losspattern" = "loss: 0%" ];
then
subject="Clear-${smokename}-Alert: $target host: ${hostname}"
else
subject="${smokename}Alert: ${target} – ${hostname}"
fi
echo "MTR Report for hostname: ${hostname}" > /tmp/mtr.txt
echo ""  >> /tmp/mtr.txt
echo "sudo mtr -n –report ${hostname} "
sudo /usr/sbin/mtr -n –report ${hostname} >> /tmp/mtr.txt
echo "" >> /tmp/mtr.txt
echo "Name of Alert: " $alertname >> /tmp/mtr.txt
echo "Target: " $target >> /tmp/mtr.txt
echo "Loss Pattern: " $losspattern >> /tmp/mtr.txt
echo "RTT Pattern: " $rtt >> /tmp/mtr.txt
echo "Hostname: " $hostname >> /tmp/mtr.txt
echo "" >> /tmp/mtr.txt
echo "Full mtr command is: sudo /usr/sbin/mtr -n –report ${hostname}" >> /tmp/mtr.txt
echo "subject: " $subject
if [ -s /tmp/mtr.txt ]; then
  /usrt/smokeping/weixin.sh "s" "s" "${subject}:${hostname}:$losspattern:$rtt:$target"
fi

准备微信报警代码

#!/bin/bash
### script name weixin.sh
### send messages from weixin for zabbix monitor
### 000
### 000
### usage:   curl -s -G url 获取acessToken
### curl --data url 传送凭证调用企业号接口
### zabbix 会传送三个参数给脚本，$1 是消息接收账号，$2 报警标题， $3 报警内容

Gtoken=$(/usr/bin/curl -s -G $GURL | awk -F '"' '{print $4}')
now_time=$(date -d now)
now_timestamp=$(date -d "${now_time}" +%s)

function logMessageToFile(){
  echo "[ $1 ] - ["$(date "+%Y-%m-%d %H:%M:%S")"] - $2" >> $LOG_FILE
}

function create_tokenfile(){
echo "${now_time} > ${Gtoken}"  > ${token_file}
}

function get_Gtoken(){
GURL="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$CropID&corpsecret=$Secret"
Gtoken=$(/usr/bin/curl -s -G $GURL | awk -F '"' '{print $4}')
}

function check_token(){
        if [ -f "${token_file}" ]; then
                file_token=$(awk -F '>' '{print $2}' ${token_file})
                file_time=$(awk -F '>' '{print $1}'  ${token_file})
                file_timestamp=$(date -d "${file_time}" +%s)
                time_difference=$[${now_timestamp}-${file_timestamp}]
                if [ "${time_difference}" -gt "${options}" ]; then
                        get_Gtoken
                        create_tokenfile
                        logMessageToFile "INFO" "上次token是： ${file_token},到现在过了${time_difference} 秒, 新的token是：${Gtoken}"
                else
                        logMessageToFile "INFO"  "not need update the token, use old token ${file_token}  到现在过了${time_difference} 秒"
                        Gtoken=$(echo ${file_token})
                fi
        else
                get_Gtoken
                logMessageToFile "INFO" "the token_file : ${token_file} not exsits ,will create it . 到现在过了${time_difference} 秒"
                create_tokenfile
        fi

}


function body(){
        local int AppID=1                  # 企业号中的应用ID
        local UserID="@all"                  # 部门成员id，zabbix中定义的微信接受者
        local PartyID="1"                # 部门id，定义了范围，组内成员都可接收到消息
        local Msg=$(echo "$@" | cut -d " " -f3-) # 过滤出zabbix中传递的第三个参数
        printf '{

        printf '	"touser":"'"$UserID""",

        printf '	"toparty":"'"$PartyID""",
"
        printf '	"msgtype": "text",'"

        printf '	"agentid":'$AppID\,"
"
        printf '	"text":{

        printf '		"content":"'"$Msg""
        printf '
	},
'
        printf '	"safe":"0"
'
        printf '}
'
}

check_token
#smokeping_alert=${1}-${2}-${3}-${4}-${5]
/usr/bin/curl --data-ascii "$(body $1 $2 $3)" $PURL

# smokeping 配置文件 config中需要修改的参数
# to 后面默认是 填写 邮件 
# 如果 = 后面 跟上 | 代表执行用户自己的脚本
# 脚本会读入5或者6个参数：name-of-alert, target, loss-pattern, rtt-pattern, #     hostname,[raise]。
*** Alerts ***
#to = |/opt/smokeping/alert.sh
to =test@test.com
from = smokealert@company.xy

# 报警条件
+someloss
type = loss
# in percent
pattern = >0%,*12*,>0%,*12*,>0%
comment = loss 3 times  in a row
# 意思是  12次检查中 出现了 3次丢包的情况

监控主机参数增加
 alerts = someloss

后续规则可以自己调整

2、特定主机发送到特定用户

to 表示接受所有报警的邮箱，如果需要在特定的节点报警发送到特定的邮箱
则在该节点上增加alertee = testmonitor@139.com即可。具体可以参看/opt/smokeping/lib/Smokeping.pm源码，如下部分:

1. foreach my $addr (map {$_ ? (split /s*,s*/,$_) : ()} $cfg->{Alerts}{to},$tree->{alertee},$alert->{to}){
